Quadruple Combination
From MormonWiki
A term used by members of the Church to refer to a complete set of the Scriptures. Scriptures are generally organized either in two separate books, one containing just the Bible, and the triple combination consisting of the Book of Mormon, Another Testament of Jesus Christ, The Docrine and Covenants, and the Pearl of Great Price. Or all four are in one book together known as a 'Quadruple Combination', commonly called a Quad for short.
